# Datastore. Usage History

This report aggregates historical data to show datastore space and datastore usage statistics across a time range.

## Description

The **Datastore. Usage History** report is a linked report that is based on the Veeam Performance Report from the Veeam Report Library.

The report features a predefined list of datastore space and datastore usage performance counters. The object picker control for the report scope has a predefined filter which limits selection to Objects of the **VMware Datastore** class and Groups that include objects of the **VMware Datastore** class.

## Parameters

Data Aggregation: defines the aggregation period (Hourly or Daily).

Date/time Selection: defines the time period to analyze in the report.

Histogram: defines the type of values shown on the x-axis of the chart.

Split into sections by: defines whether the sections will be split by datastores, selected groups/objects, or counters.

Chart Options: defines the type of an object for which a separate chart will be displayed. The list of available options depends on the Split into sections by value.

Scope: defines a list of Groups or Objects to analyze in the report. The **Add Group** option returns a Group and all objects that a group contains (with all performance counter instances). The **Add Object** option returns only the selected object.

Counters: defines collection rules for performance counters to analyze in the report.

## Sample Usage

Report on the amount of free space for all datastores during this week.

### Instructions

1. Open the Datastore. Usage History report.
